Abstract

The invention relates to a data transmission method and device, computer equipment and a computer readable storage medium, and the method comprises the steps: obtaining to-be-transmitted data, and determining the priority of the to-be-transmitted data; and if the priority of the to-be-transmitted data is the highest priority and the DMA is idle, transmitting the to-be-transmitted data in a DMA mode. According to the method, after the to-be-transmitted data is received, the priority of the to-be-transmitted data is determined, and if the priority of the to-be-transmitted data is the highest, the to-be-transmitted data is immediately transmitted through DMA, so that as many data as possible can be transmitted on the premise of not influencing a key real-time transmission service.

Description

technical field [0001] The present invention relates to the field of data transmission, in particular to a data transmission method, device, computer equipment and computer-readable storage medium. Background technique [0002] With the development of information technology, a large amount of business data needs to be transmitted between chips or systems, and these data have obvious effectiveness, such as real-time collected video frames or captured picture frames. At the same time, there are many other information to be transmitted between the chip and the system, but the transmission of real-time data cannot be disturbed during the transmission process, and the resources that these information must consume are as low as possible. When a special situation occurs, it must have the characteristics of strong real-time performance. [0003] Traditionally, the data transmission schemes are relatively general, that is, they can solve all types of data communication problems, but...
